In today’s age of rapid advances in science and technology, there is no dearth of learning material available to the avid learner. However, in the field of Otorhinolaryngology and Head and Neck Surgery, there seemed a lacuna between undergoing surgical training at various places and understanding the concepts/rationale behind the surgical technique. This book is a modest attempt by the editors to bridge this lacuna by going through each surgery in a simple step-wise manner using intraoperative images and illustrated figures, wherever required, to help understand the technique of surgery.  This is essentially an atlas and hence, the stress on learning through intraoperative images and illustrations, making it easy for the trainee as well as the ENT consultant to follow the surgery. The authors are masters in the field and this is a mammoth compilation from more than 30 countries from all over the world since knowledge cannot be bound by any barriers.
